Co-written by Spelling, it focuses on two former co-stars of a mystery show who reunite to solve real crimes.

Spelling told US Weekly: "[The show] was just the perfect vehicle for me and Jennie. I just thought it would be a great thing for us to do together."

The pair, who starred together in Beverley Hills, 90210, briefly reunited when they made cameos on the show's remake 90210.

Spelling said: "We did the new 90210 on The CW. I did two episodes of that, so we acted together again after all the years, but it'll be our first time doing a comedy together, which is really exciting."

She added: "I love performing and I love doing comedy, and it's funny, in my mind that's what I think I excel at, and it's funny that people don't know me for comedy.

"I put acting kind of on the back burner doing reality and building my brand for so many years that it'll be nice to go back to TV and do something scripted."

Spelling also said that she is looking forward to spending time with her friend's family. She has four children with husband Dean McDermott, while Garth has three from her former marriage to Twilight star Peter Facinelli.

"We haven't actually connected with our kids in years, so it'll be nice because they're all going to come to set and will be reunited there," she explained. "All our brood - my four kids and her three. Big group!"
